This manual was developed using information compiled during the National Mango Board-sponsored 2007-09 research project "Monitoring and evaluation of the mango supply chain to improve mango quality" (conducted from December 2007 through April 2009). It includes quality-control procedures to use when monitoring the maturity and quality of mangos in commercial handling operations in the USA. (For the English edition see the Bulletin of the IIR, reference 2010-2103.) Extract from the table of contents: harvest and postharvest process map for fresh mangos; harvest; transport to packinghouses and to retail stores; post-hot-water treatment cooling; cooling prior to shipping; storage rooms; storage at importer/distribution center; mango ripening; storage in walk-in coolers at stores; palletization and staging for cooling/storage/shipping; unloading at stores/holding on docks at stores; stocking and display preparation and rotation. In the appendix: quality control procedures; determining mango fruit maturity; temperature management practices; measuring relative humidity, air velocity, and pressure drops in storage rooms, trailers, or containers; trailer and container inspection and loading practices; refrigerated container/trailer loading diagram; evaluating mango ripening facilities and practices; causes and symptoms of the major defects; mango quality assessment procedures.

Studies were conducted to describe flavor and aroma in ripe tomatoes stored at 5, 10, 12.5 and 20 °C. Fruit stored for 2 d below 20 °C were rated by trained sensory panelists as significantly lower (P < 0.05) in ripe aroma, tomato flavor, compared to those stored at 20 °C. Fruit stored at 5 °C for 4 d were rated significantly lower in ripe aroma, sweetness, tomato flavor, and significantly higher in sourness, compared to those stored at 20 °C. Following 8 and 12 d storage, fruit at 5 °C were rated lowest in ripe aroma and sweetness. Significant reductions in important GC aroma volatiles and chemical composition and electronic nose analyses concurred with sensory

The effect of physiological maturity at harvest on ripe tomato (Lycopersicon esculentum Mill.) volatile profiles was studied using ripening response time (in days) to 100 μL·L-1 exogenous ethylene treatment as a tool to separate immature-green from mature-green fruit. Electronic nose (EN) sensor array and gas chromatography (GC) analyses were used to document volatile profile changes in tomatoes that required a 1-, 3-, or 5-day ethylene treatment to reach the breaker stage. EN output analysis using multivariate discriminant and canonical analyses classified intact tomato and whole tomato homogenate samples that required 3 or 5 days of ethylene treatment as significantly different (P < 0.01) from those that required only 1 day. The GC aroma profiles from whole tomato homogenate showed that 1-day fruit had significantly higher levels (P < 0.05) of 1-penten-3-one, cis-3-hexenal, 6-methyl-5-hepten-2-one, 2-isobutylthiazole, and geranylacetone when compared to 5-day fruit. Analysis of excised tomato tissues showed that pericarp (including columnella) produced an average 219% greater concentration of the 16 aroma volatiles quantified by GC when compared to locular gel (442 and 203 μL·L-1, respectively). EN analysis concurred with GC by showing greater average Mahalanobis distance between pericarp tissue groupings when compared to locular gel groupings (78.25 and 12.33 units, respectively). Pericarp tissue from the 5-day ethylene treatment showed significantly lower levels of 1-penten-3-one, trans-2-heptenal, 6-methyl-5-hepten-2-one, 2-isobutylthiazole, geranylacetone, and β-ionone compared to the 1- and 3-day treatments, Similarly, locular gel from the 3- and 5-day ethylene treatments had significantly lower levels of 1-penten-3-one, 2-isobutylthiazole, and 1-nitro-2-phenylethane compared to 1-day samples. cis-3-Hexenol in locular gel was the only volatile compound that showed significantly higher levels with increasing ethylene treatment. EN analysis showed greater Mahalanobis distances between 1- and 3-day ethylene samples than between 3- and 5-day ethylene samples (32.09 and 12.90, 24.14 and 6.52, 116.31 and 65.04, and 15.74 and 13.28 units, for intact tomato, whole tomato, pericarp, and locular gel homogenate, respectively).

`Agriset-761' and `CPT-5' tomato fruits were harvested at green stage and subsequently exposed to a postharvest exogenous ethylene-air mixture (100 ppm C2H4 at 20°C). Tomatoes with visual symptoms of ripening (breaker stage =
